<p>Parker Technology (Prof. Greg Parker) will be making a batch of high-power Xenon flash units for early 2016. Using a new capacitor and having spoken to a number of potential users the spec is:<br>

1) Light output power 100 Joules.<br>

2) Light pulse duration 25-microseconds (1/40,000th of a second).<br>

3) Recharge time <5 seconds.<br>

4) Size of flash head 230mm x 180mm x 165mm (deep)<br>

The flash head is powered by a 12 Volt dry battery unit also supplied with the head, a charger for the battery is also included.<br>

Estimated cost £2,000 plus VAT at 20% plus p&p.<br>

If you have any interest in this equipment contact Prof. Greg Parker on gregjparker@live.co.uk </p>

<p>The Licence Agreement between Laserscribe Ltd. and Parker Technology was formally terminated on 01/07/2015. If you wish to purchase custom-built portable high-power, high-speed Xenon flashguns contact Prof. Greg Parker at http://www.concept2innovation.com/ </p>

<p>If anybody on this Forum (or anybody you know) has purchased either a "Pro" or an "Ultra" microflash unit during 2014 from Laserscribe, Ely, Cambridge, U.K. (highspeedflash.com) could you please e-mail me on gregjparker@live.co.uk with details of the purchase?<br /><br />Many thanks,<br>

An image I took of a water drop collision and a bubble burst using 3 "Ultra" units is in this year's Royal Photographic Society's Science Exhibition.<br>

In the last couple of months highspeed flash dot com have sold over 15 units, many to a company specialising in "bullet time" photography. High-speed bullet-time work - great idea!<br>

<p>The guys at highspeedflash dot com http://www.highspeedflash.com/ have considerably dropped the prices of their units (for Christmas?). So if you want a unique portable high-power high-speed flash unit for your photographic assignment - now is the time :)<br>

You can see a selection of images taken with the 9-microsecond "Ultra" unit on my Flickr site <a href="http://www.flickr.com/photos/12801949@N02/">http://www.flickr.com/photos/12801949@N02/</a> <br>

Have a great 2010 - after all it's the year we make contact!<br /><br />Greg Parker </p><div></div>

<p>I just had to put up this latest image taken using 3 Ultra flash units and a sound trigger. Looks like the paranormal at work. Note that the pellet has penetrated the right hand side of the balloon completely, but at this moment in time no water can be seen escaping :)<br>

<p>Sorry to hear you feel the units are quite expensive. My perception is that for a unit that is quite unique, and with no competitors with regard to performance - they are very reasonably priced. My opinions on trying to use regular flashguns to do the job of specialist units can be read on the highspeedflash dot com web site.<br>

Greg</p>

<p>Your suspicions are completely unfounded. Why not simply e-mail them and get the facts? It costs nothing to do so.<br>

<p>Hi Ed,<br>

I think you'll find one of the pages asks you what unit you are interested in for providing a quotation.</p>

<p>Regards,<br>

Greg</p>

 

<p>Today I had some fun in a photographic studio with the "Ultra" units taking very high speed shots of bursting balloons full of water. Take a look at these results on my Flickr site http://www.flickr.com/photos/12801949@N02/ I think you'll be amazed at the stopping power (and the light output) of these units. All photos taken with a Canon 40D and 17-55mm lens at ISO 200 and f#22.<br>

<p>I just spent today getting some high speed flash images of water drops. Rather than put the pictures up here, please just check out my Flickr site to see what I've been up to at this address <a href="http://www.flickr.com/photos/12801949@N02/">http://www.flickr.com/photos/12801949@N02/</a> <br>

These images were taken using 3 "Ultra" units from <a href="http://www.highspeedflash.com">http://www.highspeedflash.com</a> a Canon 40D and a Canon 100mm macro lens. A long way to go to match Martin Waugh's standard, but then these shots were all taken manually with an electronic switch (to fire the camera and flashes) in one hand, and a syringe full of water in the other - no synchronisation, no triggering, no delay - zilch.<br>

<p>July 4th 2009 - just been playing with 3 "Ultra" units in the garage this afternoon. They punch out a LOT of light - all in 9 microseconds too :)<br>
